Biblatex with apa6 package on Ubuntu

I am trying to get the apa6 package to work on Ubuntu 12.04 (Precise). In order to do so, I first installed TeX Live2012 from texlive-backports, and after some trying installed the following packages:

#install fonts
sudo apt-get install texlive-fonts-recommended texlive-fonts-extra

#install apa6/biblatex stuff
sudo apt-get install biblatex biblatex-dw
sudo apt-get install texlive-publishers


The sample document that is included in the apa6 package now almost compiles, the only thing that is not working is the citations. At every occurrence of \textcite or \parencite, it throws an error:

There are several problems at this line:
-'\parencite' not defined by citation style.
-Package biblatex Error: Command '\cite' undefined. A three-author paper \parencite


Am I missing some dependency?

Doesn't apa6 rely on its own BibTeX(!) apacite package for citations/bibliography? – jon Oct 12 '12 at 23:35
That's a typical set of errors to get if you press on with typesetting a file where you have tried to load a biblatex style that does not exist. Without seeing logs I couldn't be sure, but I think you are probably missing the biblatex-apa files, which are in the biblatex-apa package. Check the logs and try kpsewhich apa.bbx. – Paul Stanley Oct 13 '12 at 7:15
@jon Whether it does or not, I don't think that's the problem here. The OP's source if correctly set up for biblatex, which is complaining in a way that suggests it hasn't been fed files it needs. – Paul Stanley Oct 13 '12 at 7:19

Thank you all for the comments. I solved the problem by installing the Ubuntu/Debian package texlive-bibtex-extra.
sudo apt-get install texlive-bibtex-extra

In retrospect I should probably have been able to figure this out myself, although I am not quite sure what the reasoning of the texlive maintainers is to break it up like this... I would assume that both the texlive-publishers and biblatex Debian packages would take care the of required biblatex dependencies.
